Parse社区已经多次提出PFUser通过解析后台调用从线程争用中死锁的问题,但是Parse选择不在框架中处理这个巨大的bug.有谁知道这个问题的解决方法？

我刚刚开始使用OS X 10.9.5上的Twitter Storm框架。但是，在storm-starter中运行示例拓扑时遇到了一个问题：https : //github.com/apache/storm/tree/master/examples/storm-starter。

按照自述文件，我尝试通过调用在本地部署拓扑

sudo mvn exec:java -Dstorm.topology=storm.starter.WordCountTopology

拓扑运行不到一分钟，然后以错误终止：
